Value
tack (min) = (time_ack × T) – (tskew1 + tskew2)
tenv (min) = (time_env × T) – (tskew1 + tskew2)
tenv (max) = (time_env × T) + (tskew1 + tskew2)
tdvs = (time_dvs × T) – (tskew1 + tskew2)
tdvs = (time_dvh × T) – (tskew1 + tskew2)
tcyc = time_cyc × T – (tskew1 + tskew2)
t2cyc = time_cyc × 2 × T
trfs = 1.6 × T + tsui + tco + tbuf + tbuf
tdzfs = time_dzfs × T – (tskew1)
tss = time_ss × T – (tskew1 + tskew2)
tdzfs_mli =max (time_dzfs, time_mli) × T – (tskew1 + tskew2)
tli1 > 0
tli2 > 0
tli3 > 0
tcvh = (time_cvh ×T) – (tskew1 + tskew2)
ton = time_on × T – tskew1
toff = time_off × T – tskew1
